It may not be an issue, the spell checker is simply a nice hint, but isn't essential to determine errors.
It's a good summary of the situation. I've felt that as long as the message took under a second to generate, it was ok. Realistically, I don't see anyone using identifiers as long as you tested unless they were machine generated.
In my own code, I've found the spell checker is more than a nice hint. Most of the time it nails it and speeds fixing the problem because I don't need to myself go and manually look up the correct spelling.
Iterating through the symbol table is not impossible, it's just a lot of work as it is not designed for that. There are also some issues with shadowing. Furthermore, I'd like the speller to work with the symbol table in the C++ compiler, too, which I don't wish to reimplement.
